# Shaft Friction Calculator Online

The Shaft Friction Calculator is a valuable tool utilized in engineering and construction, specifically for assessing the resistance encountered between the pile shaft and surrounding soil. It enables professionals to determine the shaft frictional force acting on a pile under specific conditions.

The Shaft Friction Calculator serves as a crucial instrument in determining the force exerted between a pile shaft and the soil it is embedded in. The formula utilized in this calculation is:

### Formula of Shaft Friction Calculator

Qs = π * D * L * τ

Where:

• D represents the diameter of the pile shaft.
• L indicates the length of the pile shaft in contact with the soil.
• τ signifies the average unit shaft friction.

This calculation aids in evaluating the magnitude of frictional forces along the pile shaft, providing essential data for structural design and construction planning.
